Install Valve Rod
1. Insert the valve rod (5104-2-1) into the gun block through the resin side. Use a
packing tool to center the valve rod.
Note: Make sure that the valve rod is correctly aligned; the larger hole goes on
the resin side, while the smaller hole goes on the catalyst side.
Note: The middle hole, into which the actuating stem will be inserted, must also
be correctly aligned. One end of the hole has a relief; and this relief should face
out of the gun block, as this is where the actuating stem will be installed.
Reinstall Actuating Stem
1. Screw the actuating stem (5104-11-1) into the valve rod (5104-2-1) thru the
center spacer.
Note: Make sure the actuating stem is screwed into the side of the valve rod with
the larger hole (thread relief).
2. Look down the front of the gun while moving the actuating stem back and forth.
You should be able to see the holes open and close. Set the actuating stem so
that the holes are closed.
